Other atresia and stenosis of urethra and bladder neck

This code signifies a congenital narrowing or complete closure of the urethra or bladder neck, not otherwise specified as a posterior urethral valve or other specific type. These malformations obstruct urine flow from the bladder, potentially leading to hydronephrosis, recurrent urinary tract infections, and renal dysfunction.

Assign this code when documentation specifies a congenital atresia or stenosis of the urethra or bladder neck that doesn't fit a more specific ICD-10-CM code. This includes conditions like congenital urethral stricture or congenital bladder neck contracture when the specific type (e.g., posterior urethral valve) is not identified. Supporting documentation should clearly indicate the congenital nature and location of the obstruction.

• Do not use this code for acquired urethral or bladder neck strictures; refer to codes in N35.x for acquired conditions.
• Always review documentation for specificity regarding the type of atresia or stenosis (e.g., posterior urethral valve) to ensure the most precise code is selected.
• Consider sequencing this code as a primary diagnosis when it is the main reason for the encounter, especially for surgical correction or initial evaluation.
